I don't see TE_ENV_H1/H2_DPDK_DRIVER set anywhere in the default configurations for the Intel X710. Do these default to vfio-pci= ? We have IOMMU enabled on our development testbed, and should be able to bind vfio-pci. Here is the text log from a run on our Intel XL710 NICs, with the expected result profile set to the X710. We haven't set up the Jenkins integration yet, however if this is required to import the logs then we will prioritize that. log.txt.tar.gz Thanks, Adam On Mon, Sep 18, 2023 at 11:04=E2=80=AFAM Andrew Rybchenko < andrew.rybchenko@oktetlabs.ru> wrote: > On 9/18/23 17:44, Adam Hassick wrote: > > Hi Andrew and Konstantin, > > Thank you for adding the tester-dial feature, this opens up the > possibility for us to do CI integrated testing in the future. > > Our Mellanox pass rate is similar to yours (about ~2400 passing, ~4400 > failing), however our Intel pass rates are far worse. > I will try running tests on the XL710 with the trc-tags argument set and > see if it improves the pass rate. > Another thing I noticed in the results you uploaded is that the results > are tagged with vfio-pci and not i40e. > Though in the environment dump, the driver on the test machine and the DU= T > are set to use the i40e driver.

Hi Andrew,

Ok, that makes= sense. I don't see TE_ENV_H1/H2_DPDK_DRIVER set anywhere in the defaul= t configurations for the Intel X710. Do these default to vfio-pci?
We have IOMMU enabled on our development testbed, and should be able = to bind vfio-pci.
Here is the text log from a run on our Inte= l XL710 NICs, with the expected result profile set to the X710. We haven= 9;t set up the Jenkins integration yet, however if this is required to impo= rt the logs then we will prioritize that.

Thanks,
Adam

Hi Andrew and Konstantin,

Thank you for adding the tester-dial feature, this opens up the possibility for us to do CI integrated testing in the future.

Our Mellanox pass rate is similar to yours (about ~2400 passing, ~4400 failing), however our Intel pass rates are far worse.
I will try running tests on the XL710 with the trc-tags argument set and see if it improves the pass rate.
Another thing I noticed in the results you uploaded is that the results are tagged with vfio-pci and not i40e.
Though in the environment dump, the driver on the test machine and the DUT are set to use the i40e driver. Is this important at all?

I think it is a misunderstanding here. There are two kinds of driver in configuration: net driver and so-called DPDK driver.
Net driver is a Linux kernel network device driver used on Tester side.
DPDK driver is a Linux kernel driver to bind device to to use it with DPDK. So, it is NOT a driver inside DPDK (drivers/net/*).
In the case of bifurcated driver (like mlx5_core) it is the same in both cases.
In non-bifurcated case DPDK driver is some UIO driver(vfio-pci, uio-pci-generic or igb_uio).
Some expectations depend on used UIO. For example, uio-pci-generic do not support many interrupts (used by usecases/rx_intr test cases).
That's why we care corresponding TRC tag.

TE_ENV_*_DPDK_DRIVER variables should be vfio-pc=C2=A0 in 710's Int= el case. Or uio-pci-generic if IOMMU is turned off on corresponding machines and Linux distro does not support VFIO no IOMMU mode.

Andrew.

There isn't anything preventing us from pushing our results up to the existing Bublik instance running at ts-factory.io that I can think of at the moment.
We will have to work out how to submit our results to your Bublik instance in a controlled and secure manner in that case.
As far as I know we won't need access controls for the results themselves. I'll discuss this with Patrick and will let you know once we confirm that it's fine.

Thanks,
Adam

Hi Andrew,

should we always auto-assign the tags or you don=E2=80=99t do it since it slows down (by some seconds) the TE startup?


Tags are auto-assigned, but I guess it differs in Adam's case since NIC is a bit different. Below test will help to understand if it is the root cause of very different expectations. If pass rate will be close to mine, I'll simply update TRC database to share expectations for mine NIC and NIC used by Adam.

Hi Adam,

I think I second the question from Andrew - happy to help you with the triage so that we get to the same baseline. Do you have a good way for us to share the logs? I.e. say upload to ts-factory if we add strict permissions system so it=E2=80=99s not publishing or any other way.

Thanks,
Konstantin

Hi Adam,

I've uploaded fresh testing results to ts-factory.io [1] to be on the same page.

I think I know why your and mine results on Intel 710 series NICs differ so much. Testing results expectations database (dpdk-ethdev-ts/trc/*) is filled in in terms of TRC tags.=C2=A0 I.e. expectatio= ns depends on TRC tags discovered by helper scripts when testing is started. These tags identify various aspects of what is tested. Ideally expectations should be written in terms of root cause of the expected behaviour. If it is a driver expectations, driver tag should be used. If it is HW limitation, tags with PCI IDs should be used. However, it is not always easy to classify it correctly if you're not involved in driver development. So, in order case expectations for 710's Intel are filled in in terms of PCI IDs. I guess PCI ID differ in your case and that's why expectations filled in for my NIC do not apply to your runs.

Just try to add the following option when you run on your 710's Intel in order to mimic mine and se= e if it helps to achieve better pass rate.
--trc-tag=3Dpci-8086-1572

BTW, fresh TE tag v1.21.0 has improved algorithm to choose tests for --tester-dial option. It should have better coverage now.<= br>

If you want stable set, you should pass --tester-random-seed=3D0 (or other integer). It is the first sketch and we have plans to improve it, but feedback would be welcome.

> Is it needed on the tester?

It is hard to say if it is strictly required for simple tests. However, it is better to update Tester as well, since performance tests run DPDK on Tester as well.

> Are there any other manual setup steps for these devices that I might be missing?

I don't remember anything else.

I think it is better to get down to details and take a look at logs. I'm ready to help with it and explain what's happening there. May be it will help to understand if it is a problem with setup/configuration.

Text logs are not very convenient. Ideally logs should be imported to bublik, however, manual runs do not provide all required artifacts right now (Jenkins jobs generate all required artifacts).
Other option is 'tmp_raw_log' file (should = be packed to make it smaller) which could be converted to various log formats.
Would it be OK for you if I import your logs to bublik at ts-factory.io? Or is it a problem that it is publicly available?
Would it help if we add authentication and access control there?

Andrew.

Hi Andrew,

I have a couple questions about needed setup of the NICs for the ethdev test suite.

Our MCX5s and XL710s are failing the checkup tests. The pass rate appears to be much worse on the XL710s (40 of 73 tests failed, 3 passed unexpectedly).

For the XL710s, I've updated the driver and NVM versions to match the minimum supported versions in the compatibility matrix found on the DPDK documentation. This did not change the failure rate much.
For the MCX5s, I've installed the latest LT= S version of the OFED bifurcated driver on the DUT. Is it needed on the tester?

Are there any other manual setup steps for these devices that I might be missing?

Thanks,
Adam

Hi Andrew,

Yes, I copied the X710 configs to set up XL710 configs. I changed the environment variable names from the X710 suffix to XL710 suffix in the script, and forgot to change them in the corresponding environment file.
That fixed the issue.

I got the checkup tests working on the XL710 now. Most of them are failing, which leads me to believe this is an issue with our testbed. Based on the DPDK documentation for i40e, the firmware and driver versions are much older than what DPDK 22.11 LTS and main prefer, so I'll try updating those.

For now I'm working on getting the XL71= 0 checkup tests passing, and will pick up getting the E810 configured properly next. I'll let you know if I run into any more issues in relation to the test engine.

Thanks,
Adam

Hi Andrew,

The compilation warning issue is now resolved. Again, thank you guys for fixing this for us. I can run the tests on the Mellanox CX5s again, however I'm running int= o a couple new issues with running the prologues on the Intel cards.

When running testing on the Intel XL710s, I see this error appear in the log:

ERROR =C2=A0prologue =C2=A0Enviro= nment LIB =C2=A014:16:13.650
Too few networks in available configuration (0) in comparison with required (1)

This seems like a trivial configuration error, perhaps this is something I need to set up in ts-rigs. I briefly searched through the examples there and didn't see any mention of how to set up a network.
I will attach this log just in case you need more information.

Unfortunately logs are insufficient to understand it. I've pushed new tag to TE v1.19.0 which add log message with TE_* environment variables.
Most likely something is wrong with variables which are used as conditions when available networks are defined in ts-conf/cs/inc.net_cfg_pci_fns.yml:
TE_PCI_INSTANCE_IUT_TST1
TE_PCI_INSTANCE_IUT_TST1a
TE_PCI_INSTANCE_TST1a_IUT
TE_PCI_INSTANCE_TST1_IUT
My guess it that you change naming a bit, but script like ts-rigs-sample/scripts/iut.h1-x710 is not included or not updated.

There is a different error when running on the Intel E810s. It appears to me like it starts DPDK, does some configuration inside DPDK and on the device, and then fails to bring the device back up. Since this error seems very non-trivial, I will also attach this log.

This one is a bit simpler. Few lines after the first ERROR in log I see the following:
WARN=C2=A0 RCF=C2=A0 DPDK=C2=A0 13:06:00.= 144
ice_program_hw_rx_queue(): currently package doesn't support RXDID (22) ice_rx_queue_start(): fail to program RX queue 0
ice_dev_start(): fail to start Rx queue 0
Device with port_id=3D0 already stopped
It is stdout/stderr from test agent which runs DPDK. Same logs in plain format are available in ta.DPDK file.
I'm not an expert here, but I vaguely remember that E810 requires correct firmware and DDP to be loaded.
There is some information in dpdk/doc/guides/nics/ice.rst.

You can try to add --dev-args=3Dsafe-mode-support=3D1 command-line option described there.

Hope it helps,
Andrew.

Hi Andrew,

I have one additional question as well: Does the test engine support running tests on two ARMv8 test agents?

1. We'll sort out warnings this week. Thanks for heads up.

Great. Let me know when that's fixed.

Done. We also fixed a number of warnings in TE.
Also we fixed root test package name to be consistent with the repository name.

Support for old LTS branches was dropped some time ago, but in the future it is definitely possible to keep it for new LTS branches. I think 22.11 is supported, but I'm not sure abou= t older LTS releases.

Good to know.
=C2=A0
2. You can add command-line option --sanity to run tests marked with TEST_HARNESS_SANITY requirement (see dpdk-ethdev-ts/scripts/= run.sh and grep TEST_HARNESS_SANITY dpdk-ethdev-ts to see which tests are marked). Yes, there is a space for terminology improvement here. We'll do it.

Done. Now it is called --checkup.


Also it takes a lot of time because of failures and tests which wait for some timeout.

That makes sense to me. We'll use the tim= e to complete tests on virtio or the Intel devices as a reference for how long the tests really take to complete.
We will explore the possibility of periodically running the sanity tests for patches.

I'll double-check and let you know how long entire TS runs on Intel X710, E810, Mellanox CX5 and virtio net. Just to ensure that time observed in your case looks the same.

=C2=A0
The test harness can provide coverage reports based on gcov, but I'm not sure what you mean by a "dial" t= o control test coverage. Provided reports are rather for human to analyze.

The general idea is to have some kind of parameter on the test suite, which could be an integer ranging from zero to ten, that controls how many tests are run based on how important the test is.

Similar to how some command line interfaces provide a verbosity level parameter (some number of "-v" argumen= ts) to control the importance of the information in the log.
The verbosity level zero only prints very important log messages, while ten prints everything.

In much the same manner as above, this "dial&q= uot; parameter controls what tests are run and with what parameters based on how important those tests and test parameter combinations are.
Coverage Level zero tells the suite to run a very basic set of important tests, with minimal parameterization. This mode would take only ~5-10 minutes to run.
In contrast, Coverage Level ten includes all the edge cases, every combination of test parameters, everything the test suite can do, which takes the normal several hours to run.
The values 1 - 9 are between those two extremes, allowing the user to get a gradient of test coverage in the results and to limit the running time.

Then we could, for example, run the "run.sh= " with a level of 2 or 3 for incoming patches that need quick results, and with a level of 10 for the less often run periodic tests performed on main or LTS branches.

Understood now. Thanks a lot for the idea. We'll discuss i= t and come back.

=C2=A0
3. Yes, really many tests on Mellanox CX5 NICs report unexpected testing results. Unfortunately it is time consuming to fill in expectations database since it is necessary to analyze testing results and classify if it is a bug or just acceptable behaviour aspect.

Bublik allows to compare results of two runs. It is useful for human, but still not good for automation.

I have local patch for mlx5 driver which reports Tx ring size maximum. It makes pass rate higher. It is a problem for test harness that mlx5 does not report limits right now.

Pass rate on Intel X710 is about 92% on my test rig. Pass rate on virtio net is 99% right now and could be done 100% easily (just one thing to fix in expectations).

I think logs storage setup is essential for logs analysis. Of course, you can request HTML logs when you run tests (--log-html=3Dhtml) or generate after run using dpdk-ethdev-ts/scripts/html-log.sh and open index.html in a browser, but logs storage makes it more convenient.

We are interested in setting up Bublik, potentially as an externally-facing component, once we have our process of running the test suite stabilized.
Once we are able to run the test suite again, I'll see what the pass rate is on our other hardware.
Good to know that it isn't an issue with our dev testbed causing the high fail rate.

For Intel hardware, we have an XL710 and an Intel E810-C in our development testbed. Although they are slightly different devices, ideally the pass rate will be identical or similar. I have yet to set up a VM pair for virtio, but we will soon.

Latest version of test-environment has examples of our CGI scripts which we use for log storage (see tools/log_server/READ= ME.md).

Also all bits for Jenkins setup are available. See dpdk-ethdev-ts/jenkin= s/README.md and examples of jenkins files in ts-rigs-sample.

Jenkins integration, setting up production rig configurations, and permanent log storage will be our next steps once I am able to run the tests again.
Unless there is an easy way to have meson not pass "-Werror" int= o GCC. Then I would be able to run the test suite.

Hopefully it is resolved now.

I thought a bit more about your usecase for Jenkins. I'm not 100% sure that existing pipelines are convenient for your usecase.
Fill free to ask questions when you are on it.

Thanks,
Andrew.

Hi Andrew,

That fix seems to have resolved the issue, thanks for the quick turnaround time on that patch.
Now that we have the RCF timeout issue resolved, there are a few other questions and issues that we have about the tests themselves.

1. The test suite fails to build with a couple warnings.

Below is the stderr log from compilation:

This error wasn't occurring last week, which was the last time I ran the tests.
The TE host and the DUT have GCC v9.4.0 installed, and the tester has GCC v11.4.0 installed, if this information is helpful.

2. On the Mellanox CX5s, there are over 6,000 tests run, which collectively take around 9 hours. Is it possible, and would it make sense, to lower the test coverage and have the test suite run faster?

For some context, we run immediate testing on incoming patches for DPDK main and development branches, as well as periodic test runs on the main, stable, and LTS branches.
For us to consider including this test suite as part of our immediate testing on patches, we would have to reduce the test coverage to the most important tests.
This is primarily to reduce the testing time to, for example, less than 30 minutes. Testing on patches can't take too long because the lab can receive numerous patches each day, which each require individual testing runs.

At what frequency we run these tests, and on what, still needs to be discussed with the DPDK community, but it would be nice to know if the test suite had a "dial" = to control the testing coverage.

3. We see a lot of test failures on our Mellanox CX5 NICs. Around 2,300 of ~6,600 tests passed. Is there anything we can do to diagnose these test failures?

Thanks,
Adam

Brilliant idea. If DNS returns both IPv4 and IPv6 addresses in your case, I guess it is the root cause of the problem.
Of course, it is TE problem since I see really weird code in lib/comm_net_engi= ne/comm_net_engine.c line 135.

Hi Andrew,

We have yet to notice a distinct pattern with the failures. Sometimes, the RCF will start and connect without issue a few times in a row before failing to connect again. Once the issue begins to occur, neither rebooting all of the hosts (test engine VM, tester, IUT) or deleting all of the build directories (suites, agents, inst) and rebooting the hosts afterward resolves the issue. When it begins working again seems very arbitrary to us.

I do usually try to terminate the test engine with Ctrl+C, but when it hangs while trying to start RCF, that does not work.

Does the test engine prefer to use IPv6 over IPv4 for initiating the RCF connection to the test bed hosts? And if so, is there a way to force it to use IPv4?

Done. It works fine for me without any issues.

Have you noticed any pattern when it works or does not work? May be it is a problem of not clean state after termination?
Does it work fine the first time after DUTs reboot?
How do you terminate testing? It should be done using Ctrl+C in terminal where you execute run.sh command.
=C2=A0In this cas= e it should shutdown gracefully and close all test agents and engine applications.

(I'm trying t= o understand why you've seen many test agent processes. It should not happen.)

Hi Andrew,

Two of our systems (the Test Engine runner and the DUT host) are running Ubuntu 20.04 LTS, however this morning I noticed that the tester system (the one having issues) is running Ubuntu 22.04 LTS.
This could be the source of the problem. I encountered a dependency issue trying to run the Test Engine on 22.04 LTS, so I downgraded the system. Since the tester is also the host having connection issues, I will try downgrading that system to 20.04, and see if that changes anything.

Unlikely, but who knows. We run tests (DUTs) on Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10, Ubuntu 23.04, Debian 11 and Fedora 38 every night.
Right now Debian 11 is used for test engine in nightly regressions.

I'll double-check test engine on Ubuntu 20.04 and Ubuntu 22.04.

I did try passing in the "--vg-rcf&qu= ot; argument to the run.sh script of the test suite after installing valgrind, but there was no additional output that I saw.

Sorry, I should valgrind output should be in valgrind.te_rcf (direction where you run test engine).


I will try pulling in the changes you've pushed up, and will see if that fixes anything.

I've just published a new tag which fixes known test engine side problems on Debian 12 and Fedora 38.

I was able to replicate the same behavior again, where it hangs while RCF is trying to start.
Running this command, I see this in the output:

So it seems like it is listening on the correct port.
Additionally, I was able to connect to the Tester machine from our Test Engine host using telnet. It printed the PID of the process once the connection was opened.

I tried running the "ta" application manually on the command line, and it didn't print anything at all.
Maybe the issue is something on the Test Engine side.

=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 Yes, TE_RCFUNIX_TIMEOU= T is in seconds. I've double-checked =C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 that it goes to 'copy_timeout= ' in ts-conf/rcf.conf.=
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 Description in in doc/sphinx/pages/= group_te_engine_rcf.rst
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 says that copy_timeout is in seconds and implementation in
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 lib/rcfunix/rcfun= ix.c passes the value to select() tv_sec.
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 Theoretically select() could be interrupted by signal, but I
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 think it is unlikely here.

=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 I'm not sure that I understand what do you mean by RCF
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 connection timeout. Does it happen on TE startup when RCF
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 starts test agents. If so, TE_RCFUNIX_TIMEOU= T could help. Or =C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 does it happen when tests are in progress, e.g. in the middle
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 of a test. If so, TE_RCFUNIX_TIMEOU= T is unrelated and most
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 likely either host with test agent dies or test agent itself
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 crashes. It would be easier for me if classify it if you share

=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 Hi Andrew,

=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 I've set up a test rig repository here, and have created
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 configurations for our development testbed based off of the
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 examples.
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 We've been able to get the test suite to run manually on
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 Mellanox CX5 devices once.
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 However, we are running into an issue where, when RCF starts,
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 the RCF connection times out very frequently. We aren't sure =C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 why this is the case.
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 It works sometimes, but most of the time when we try to run
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 the test engine, it encounters this issue.
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 I've tried changing the RCF port by setting
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 "TE_RCF_PORT= =3D<some port number>" and rebooting the testbed
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 machines. Neither seems to fix the issue.

=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 It also seems like the timeout takes far longer than 60
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 seconds, even when running "export TE_RCFUNIX_TIMEOU= T=3D60"
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 before I try to run the test suite.
=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0 I assume the unit for this variable is seconds?
